Main file struggles really hard, either renders mostly blurry (opened straight from on device file stores) or struggles to render at all (from Mega, ried in case it somehow removed blur which... I suppose technically...?)...
My guess was that it was just taking up too much memory when loading, which would be due to file size, but when I reexported it, it still loaded a bit slowly. I'm not entirely sure if I fixed it, so let me know, and I can get images for you instead.
